Good looking graph so far! Definitely the carbs are choking the motor up top after 9K. Your HP curve should continue to climb up and past 45 HP and your torque should stay relatively flat past 9k instead of dropping.
Do you have your AFR recorded as well? Pods and what gas were you running?

eBay for the crank and rods as well as the Wisco pistons. So this all went like this: $299 for the crank free shipping, $230 for the pistons free shipping,$304 for balancing the crank plus $30 shipping, $100 to bore the cylinders here I. Town, $110 gasket set free shipping. So about $1170 out of pocket so far. The clutch is slipping so a new Barnett is on it's way with springs. Oh ya about $35 in jets and $100 dyno time.

Well, we ran the snot out of this bike over the weekend. I raced it in the Light Weight classes and my son ran it in the Ultra Light Weight classes. I was able to race up into the SV crowd but couldnt catch the fast guys. Caught and passed most of the Buell 1200's in LW super bike/super twins combined. The weekend ended sunday with a blown head gasket. I'm thinking a bigger radiator is in order. My fastest ever lap time, at this track, on my stock bike, was a 1:23.9 but usually run around in the 1:24's, I got down into the 1:19's (1:19.2 the fastest) on several laps and consistant 1:20's.

What about an oil cooler as well? Those aren't too expensive and are likely a good idea for you.

Talk to Mordy about the gasket. I already paid the RnD for the new gen head gasket pattern. You will just need a bore change.

Perfect, I'll mention that to them.
Question for ya sorry to be off topic, but do you think the 6 main head bolts would be good enough for studs and then run a stock bolt on the 7th short bolt? |

I was mostly joking about the shop since I gotta keep my bike legal. Then again I doubt even with 40 hp I'd be able to get on the podium, so all that would happen is I'd get some disapproving looks down the straightaways... |

NOOO don't do that. And remember the stud needs to bottom out tight and still clear the cam.

Bruce, there's an oil cooler made for our bikes. There are Chinese knockoffs of the one made on eBay. Search the reviews here. @DaBlue1 has the original one

Here is some info on the engine oil cooler if your interested. back when i got mine, there were a few who were using them in races in Thailand, where Ninja 250 racing is big.. You may be able to see the cooler on the Ninja 250 in the pic below. https://www.ninjette.org/forums/show...ine+oil+cooler https://www.ninjette.org/forums/show...ght=oil+cooler |

The oil coolers in the pictures do the job just because these 250s are... 250s... no high compression, no extra ccs, just exhaust and jetting or PC Vs...you need sth way bigger... I agree of course on getting ARP studs (I wish I could get a set too...) but I don't think a special gasket will make a difference (I believe you have chaecked both head and block for warp because of taking them apart and sleeving before re-bolting them together) Trying an oil cooler will definetely help but try the biggest you can put there because it stays hot not only because of the exhaust pipes but also becuse of lack of fresh flowing air (front wheel in combination with moderate speeds aren't much of a help there) I hope you make it and get back on the track soon, having overcome those minor issues... I wish I could just watch you going past those Buells...

@bruce71198 - don't go with salad oil, your oil should be Motul 300V 15W50 100% Synthetic – Ester Core Technology (Ester means that the oil temp in higher ranges is reduced by up to 10 degrees Celsius).
The highest temps for racing oils is up to 160 deg. Celsius (some even 180 deg. C.), what you normally shouldn't reach. My Ninja here in high temperature environment when in move doesn't go above 95 deg. C., when I wait at the signals the temp. can reach app. 105 deg. C. but that all is far away from the highest value. By the way I have the oil cooler and with the Koso RX2 I can read the oil temperature also and that I measure in the main stream (not at the oil drain plug). |

I had a base CR of 13,9:1 and +2 degrees advance timing and that was part of the reason for it. Bruce has not that high a CR however the big pistons move closer to each other and heat cannot dissipate that easily in those casings and sleeves...

Also it's given that my temperature for sure is lower than a Ninja used in a race. It's important to have a good inside cooling from a rich enough setup in fuel. Your tipp from before about the Italian water cooler I think is a very good one, it also seems to be lighter than oem and at least in a bike like this I would use an electrical water pump (what brings up to 3-4 hp with the 2-fiddy). |

So I am a bit confused, is that oil cooler available in the states or no? If not is there an equivalent unit sold that we know of. Seems like a decent idea for a hard ridden bike.

I got an oil cooler from Ecotrons. Comes with hoses and fittings.
Heat is a real issue on these engines. I run WFO for a mile spray nitrous for half that distance. Fuel mixture is critical over all. But a large radiator and air flow is also important. I use engine ice for coolant. Copper head gaskets also help dissipate heat.
